RM3 TR112VS7 Product Description Telemecanique RM3 TR112VS7, also named RM3TR1 three-phase voltage monitoring relay, is a phase control relay for industrial power distribution system. It is designed to detect phase loss, phase sequence error and voltage deviation, supporting power supply abnormality protection for old automation equipment renovation.

This relay delivers reliable phase monitoring for power control tasks. The phase monitoring supports three-phase power status continuous detection. The phase monitoring realizes abnormal power condition judgment and trigger alarm output. Stable phase monitoring completes power fault early warning for mechanical equipment.

The built-in circuit processing achieves steady signal output. The signal output provides relay contact signal for PLC or contactor control. The signal output supports adjustable response delay setting. Accurate signal output ensures protection action according to power monitoring logic.

DIN rail mounting structure brings convenient cabinet installation. Cabinet installation can be directly clipped on control cabinet DIN rail. Cabinet installation connects three-phase power via screw terminal block. Flexible cabinet installation is widely used for legacy RM3 series relay spare replacement.

RM3 TR112VS7 supports phase failure, phase sequence and under/over voltage monitoring function, equipped with power wiring terminal block. It has LED status indicators for power and fault diagnosis. Widely applied in pump stations, material handling equipment and traditional production lines. This product is discontinued by Telemecanique, mainly supplied as industrial spare parts, complying with RM3 series industrial control standards.
